Hydrofarm Heat Mats Work Great for Many Things
Hydrofarm heat mats are perfect for veteran growers, beginners, and children too. They improves germination by warming the root area 10-20°F over ambient temperature. By warming the roots, you increase your growing success!
Heat mats are not just for gardening anymore! They are very useful for providing consistent, controllable heating for other hobbies, including homebrewing. Hydrofarm heat mats allow you to maintain desired fermentation temperatures in carboys, especially when used with the Jump Start Heat Mat Thermostat MTPRTC.
Another application for Hydrofarm heat mats is heating for pet enclosures and terrariums, such as those used in reptile, rodent and arachnid keeping. When used with the Jump Start Heat Mat Thermostat MTPRTC, heat mats can be controlled to provide the precise level of warmth your pets require to flourish.
The Seedling Heat Mat uses 107 watts to warm root area 10 to 20 degrees over ambient temperature and improve seed germination and increases the success of seedlings and cuttings. UL listed, waterproof construction with six foot power cord.
Top customer reviews
Update 1: mat has completely failed. I've basically used it twice since I bought it, stored flat. Made for some very expensive tomato plants. Junk.
Update 2: Their customer service wrote back refusing to replace the mat since it was >1 yr old. Interestingly, she tacitly admitted that the version I have was unreliable has been improved and the new model now has a low return rate.
Take away - this works great for kombucha, just take some precautions to make sure your brew won't get too hot.
The mat is great and does exactly what it's supposed to...creates a nice warm pad for beneath some windowsill starter "greenhouse" kits. It raises the temperature of the soil, and makes the environment within the planter even more warm and humid.
For the record, I bought both the"Jiffy 5710 12-Pellet Indoor Plant Start Greenhouse" and the "Hydrofarm JS12GH Jumpstart 12-Pellet Indoor Seed Start Greenhouse" (Sorry, Amazon wont' let me link them at the moment) and you can fit TWO of either of these on the mat...which made it a great investment. 24 plants are getting the heat. (For the record, I liked the Hydrofarm greenhouse better due to a nicer plactic lid).
BUT, the first few days I noticed that all the heat was probably going into my cold cold windowsill. SO, I picked up some cork trivets for cheap (either on Amazon or your favorite Bed and Bath type store), placed them on the windowsill, heating mat on top, and the planters on top of that. Next day the difference was very evident. Extremely foggy planters and the bottom was very warm. I think the plants are VERY appreciative. Make sure you insulate the mat or risk losing all your heat into whatever you have it placed on.
Going to pick up another one or two of these. I don't have room for the 25 planter starter greenhouses, but I can fit 2x12 in two different windowsills just fine.
This is the high quality commercial style mat, a single sheet of sturdy rubbed with the heat coils embedded. Cheaper mats are more like home heating pads, with a loose outer cover over internal heat.
I did not buy the thermostat. I set this up directly On a concrete porch floor. Today I set a blanket under it to lose less heat to the floor.
The Mat doesn't feel hot to the touch, I'm fact sometimes it doesn't feel warm. It's a very gentle heat, which is why the thermostat isn't necessary unless you're raising something finicky. I know it's working because the covers over the flats stay fogged up - they weren't before.
Anyway, don't hesitate. I'm buying another one to start my cuttings!
Fast, efficient delivery in good condition. (Pleased with Bulk Hydro as vendor. They did a separate follow-up to check on my satisfaction with the product.)
The Hydrofarm mat, large 20x48, fit well in the frame I am using for rooting European grape cuttings.
The product is a flat, fairly thick, rubber mat with an embedded heating element. It does come rolled up but I just rolled it out on the game table, let the edges hang over the side and put some weight on ends to bend them and flatten the mat.
Though we have had an unusually cold spring, the mat is presently in use and providing effective warming (worked well keeping Monarch Manufacturing 's planting sleeves above freezing at sub-freezing temps).
I was concerned that there might be some rubbery smell, but I have not noticed any.
No cons, but a caution
Not a "con" but an advisory, this is a "warming" pad and it is an electrical device. It provides about 10-20 degrees of additional heat depending on insulation. I have mat positioned so that water runs off into a sump so it is neither covered with, nor laying in, water.
As with any electrical appliance, if you cut it to make it "fit", fray the cord, or use it for some unintended purpose, you could create a serious problem.
Follow up: Used with Schultz Rooting hormone (Amazon). First bud break appeared in 15 days in spite of variable weather (actually a little too soon, I was hoping for an additional week or two to allow for root development, and had "tented" the top of the frame to keep the buds cool - five-star products in the hands of a three-star gardener).
